This invention contemplates .the .provi sion of a gauge of test cock forsteambollers and the like, wherein the discharge nipple is normallyclosed by a packing carried by a spring pressed pivoted lever, and whichpacking can be very easily and conveniently rotated from time to time topresent a new.

gauge which is adapted to be screw-threaded into the boiler, not shown,and which gauge is provided with a discharge port, which in thisspecific instance is preferably in the nature of a discharge nipple 11which is threaded or otherwise suitably associated with'one end of thegauge as shown in Figure 1. Projecting from the bodyof the gauge is abracket 'arm 12 having-spaced lugs 13 which are straddled by the separated portions 14 defined by the bifurcated extremity of a lever '15,the latterbeing;

pivoted upon the lugs 13 by the pivoted bolt 16 as clearly shown inFigure 2. Surrounding this'bolt is a coil spring 17, one end 18 of whichbears against the bracket arm 12 while the other end 19 of which bearsagainst the lever for the purpose of normally closing'the dischargenipple 11 in a manner to be hereinafter described.

The lever 15 is provided with a depending arm 20 upon which a ring gear21 is rotatably mounted and which gear includes a solid hub-like portion22 uponwhich a circular packing 23 is mounted as clearly shown inFigure3. This packing is held positioned upon the hub by means'of a disk 24chaving a slightly greater diameter than the hub-like portion 22, thedisk-beingheld. associated with the hub by means'of a thumb bolt 25,'thereby'holding the packing between the disk 24 and the ring gear 21.-It will be noted upon inspection of Figure 1 that that portion of thelever 15 which is The gauge proper Connected the' 'bracket arm 12,defines with the latter asubstantially arch-shaped portion beneath whichthe ring gear is are ranged, sothat the packing 23 is positioned toengage and normallyclose the discharge nipple 11. The lever 15 furtherincludes a hollow handle-like portion 26 in which a shaft 27 isjournaled, the shaft projecting beyond the outer end of the handle andthreaded for a portion of its length to accommodate a knob .28 throughthe, instrumentality of which the shaft 27 is rotated, and a lock nut 29for holding the shaft in a given position. Carried by the inner end ofthis shaft is a pinion. 30 meshing with the ring gear 21, so that byrotating the shaft 27, similar motion is imparted tothe gear 21 for thepurpose of presenting a new surfaceor portion of the packing 23 to thedischarge nipple :11' as the occasion mayrequire. In this manner'theentire peripheral surface of the packing may be used before replacingthe same, but when this is necessary 'it can be easilychanged byremoving the disk 24 and slipping the packing off the hub-like portion22 ofthe ring ear. a i I V :3 indicated at 10 is also provided with avalve of any wellknown construction, the manipulating wheel for which isindicatedat 31, so that this valve m i can be closed while thepacking'23, or the r discharge nipple 11 is being replaced. i

While it is believed that from the fore going description, the natureand Yadvantages of the invention will be readily apparent, I desire tohave it understood,

that I do not limit myself to what is herein shown and described andthatjsuch changes may be resorted to when desired as fall within thescope of what is claimed;

What is claimed is:

1. In combination, a gauge cock having I a discharge port, a leverpivotally mounted thereon, a mug gear ournaled on sa d lever anddependlngtherefrom, a circular packing carried by said gear and havingits periphery normally closing said port, and

means carried by the lever for rotating said gear and packing to presenta new peripheral surfaceto said port when desired.

2. In combination, a gauge cock having a discharge port, a springpressed lever pivoted on said gauge and including a hollow handleportion, a ring gear journaled on said lever, acircular packing carriedby said gear and normally closing,- said port,

I 'a, shaft journaled in said handle-like portion, a pinion carried bythe shaft and meshmg with said gear, and means for rotatlng said shaftto operate said gear and present a new surface of the packing to saidport' 3. In combination, a gauge cock havlng a discharge port, a spring:pressed pivoted lever mounted on said gauge and meludlng a handleportionnormally arranged in axial on said huh-like portion, a removable diskcarried by said portion for holding the packing therebetween and saidgear, said packing normally closing said port, a shaft journaled in saidhandle portion of the 4 lever, a pinion carried by said shaft andmeshing with said gear, and means for rotating, said shaft to operatesaid gear, and

thereby present a new surfaee of the packing to said port.
